Who can rechamber 9mm to .357 SIG?

[gcw16]

I have a CZ SP-01 barrel in 9mm that I would like to get rechambered to .357 SIG. In the SP-01 series, the 9mm and .40 barrels have the same external dimensions so the 9mm barrel can be rechambered and used in a .40 pistol. I tried Gunworks in Ohio but they don't have a .357 reamer. Anybody know someone who can do this for me?

Cz custom shop in Arizona will. I thought about buying a SP 01 and having that done. The gun needs to be a 40 and it's not cheap. They quoted me $375  for the 9mm barrel and labor. They also require the gun sent in to make sure it's fitted correctly.
